Definitions

  • This invention relates to novel triazole derivatives which have antifungal activity and are useful in the treatment of fungal infections in animals, including humans, and as plant fungicides.
  • Triazole derivatives having fungicidal activity are already known from the prior art, see for example EP-A-52424 and US-A-4243405.
  • the invention also provides a pharmaceutical composition
  • a pharmaceutical composition comprising a compound of the formula (I) or a pharmaceutically acceptable salt thereof, together with a pharmaceutically acceptable diluent or carrier.
  • the invention further provides a compound of the formula (I) or a pharmaceutically acceptable salt thereof, for use in medicine, in particular for treating fungal infections in animals, including humans.
  • the invention yet further provides a composition for use as an agricultural (including horticultural) fungicide, comprising a compound of the formula (I) or an agriculturally acceptable salt thereof, together with an agriculturally acceptable diluent or carrier.
  • the invention yet further provides a method of treating a plant or seed having a fungal infection, which comprises contacting said plant or seed, or the locus of said plant, with an effective amount of a compound of the formula (I) or agriculturally acceptable salt thereof.
  • n is 1, 2 or 3.
  • the compounds of the formula (I) can be prepared as follows:- where Q is a leaving group such as Cl, Br, I, CF 3 SO 2 O ⁇ , CH 3 S0 2 0- or p-toluenesulphonyloxy, and M is preferably Na, K or Li.
  • the starting materials of the formula (II) can be obtained in a conventional manner, e.g.
  • Pharmaceutically acceptable acid addition salts of the compounds of the formula (I) are those formed from strong acids which form non-toxic acid addition salts, such as hydrochloric, hydrobromic, sulphuric, oxalic and methanesulphonic acids.
  • the salts may be obtained by conventional procedures, e.g. by mixing solutions containing equimolar amounts of the free base and desired acid, and the required salt is collected by filtration, if insoluble, or by evaporation of the solvent.
  • the compounds of the formula (I) and their pharmaceutically acceptable salts are antifungal agents, useful in combating fungal infections in animals, including humans.
  • they are useful in treating topical fungal infections in man caused by, among other organisms, species of Candida, Trichophyton, Microsporum or Epidermophyton, or in mucosal infections caused by Candida albicans (e.g. thrust and vaginal candidiasis).
  • They can also be used in the treatment of systemic fungal infections caused by, for example, Candida albicans, Cryptococcus neoformans, Aspergillus fumigatus, Coccidioides, Paracoccidioides, Histoplasma or Blastomyces.
  • the in vitro evaluation of the antifungal activity of the compounds can be performed by determining the minimum inhibitory concentration (m.i.c.) of the test compounds in a suitable medium at which growth of the particular micro-organism fails to occur.
  • m.i.c. minimum inhibitory concentration
  • a series of agar plates, each having the test compound incorporated at a particular concentration is inoculated with a standard culture of, for example, Candida albicans and each plate is then incubated for 48 hours at 37°C. The plates are then examined for the presence or absence of growth of the fungus and the appropriate m.i.c. value is noted.
  • micro-organisms used in such tests can include Cryptococcus neoformans, Aspergillus fumigatus, Trichophyton spp; Microsporum spp; Epidermophyton floccosum, Coccidioides immitis and Torulopsis glabrata.
  • the in vivo evaluation of the compounds can be carried out at a series of dose levels by intraperitoneal or intravenous injection or by oral administration, to mice which are inoculated with a strain of Candida albicans. Activity is based on the survival of a treated group of mice after the death of an untreated group of mice following 48 hours observation. The dose level at which the compound provides 50% protection against the lethal effect of the infection (PO so ) is noted.
  • the antifungal compounds of the formula (I) can be administered alone, but will generally be administered in admixture with a pharmaceutical carrier selected with regard to the intended route of administration and standard pharmaceutical practice.
  • a pharmaceutical carrier selected with regard to the intended route of administration and standard pharmaceutical practice.
  • they can be administered orally in the form of tablets containing such excipients as starch or lactose, or in capsules or ovules either alone or in admixture with excipients, or in the form of elixirs or suspensions containing flavouring or colouring agents.
  • They can be injected parenterally, for example, intravenously, intramuscularly or subcutaneously.
  • parenteral administration they are best used in the form of a sterile aqueous solution which may contain other substances, for example, enough salts or glucose to make the solution isotonic with blood.
  • the daily dosage level of the antifungal compounds of the formula (I) will be from 0.1 to 10 mg/kg (in divided doses) when administered by either the oral or parenteral route.
  • tablets or capsules of the compounds will contain from 5 mg to 0.5 g of active compound for administration singly or two or more at a time as appropriate.
  • the physician in any event will determine the actual dosage which will be most suitable for an individual patient and it will vary with the age, weight and response of the particular patient.
  • the above dosages are exemplary of the average case; there can, of course, be individual instances where higher or lower dosage ranges are merited, and such are within the scope of this invention.
  • the antifungal compounds of formula (I) can be administered in the form of a suppository or pessary, or they may be applied topically in the form of a lotion, solution, cream, ointment or dusting powder.
  • they can be incorporated into a cream consisting of an aqueous emulsion of polyethylene glycols or liquid paraffin; or they can be incorporated, at a concentration between 1 and 10%, into an ointment consisting of a white wax or white soft paraffin base together with such stabilizers and preservatives as may be required.
  • the compounds of the formula (I) and their salts also have activity against a variety of plant pathogenic fungi, including for example various rusts, mildews and moulds, and the compounds are thus useful for treating plants and seeds to eradicate or prevent such diseases.
  • the in vitro evaluation of the activity of the compounds against plant fungi can be determined by measuring their minimum inhibitory concentrations in the same way as previously described except that the plates are incubated at 30°C for 48 hours or longer before being examined for the presence or absence of growth.
  • Micro-organisms used in such tests include Cochliobolus carbonum, Pyricularia oryzae, Glomerella cingulata, Penicillium digitatum, Botrytis cinerea and Rhizoctonia solani.
  • the compounds and their agriculturally acceptable salts are preferably used in the form of a composition formulated as appropriate to the particular use and purpose desired.
  • the compounds may be applied in the form of dusting powders, or granules, seed dressings, aqueous solutions, dispersions or emulsions, dips, sprays, aerosols or smokes.
  • Compositions may also be supplied in the form of dispersible powders, granules or grains, or concentrates for dilution prior to use.
  • Such compositions may contain such conventional carriers, diluents or adjuvants as are known and acceptable in agriculture and horticulture and they are manufactured in accordance with conventional procedures.
  • compositions may also incorporate other active ingredients, for example, compounds having herbicidal or insecticidal activity or a further fungicide.
  • active ingredients for example, compounds having herbicidal or insecticidal activity or a further fungicide.
  • the compounds and compositions can be applied in a number of ways, for example they can be applied directly to the plant foliage, stems, branches, seeds or roots or to the soil.
